Built on the HSCO135 series, it features a 135-degree split point that reduces walking and starts on contact without a center punch. The web-thinned, parallel web construction reduces thrust and extends tool life. At 2-1\/16 inches overall length, the stub-length body provides rigidity for accurate, chatter-resistant holes. This bit is suited for licensed machinists, maintenance technicians, and trade professionals drilling ferrous metals, stainless steel, and hard alloys where standard HSS bits wear prematurely.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are a standard choice in metal fabrication shops, maintenance and repair operations, and production environments where short, rigid tooling is required. The Size 23 wire gauge designation corresponds to 0.154 inches, placing it in the 0.150 to 0.200 inch diameter range. Its right-hand cutting direction and regular spiral flute are compatible with conventional drill presses, CNC machining centers, and hand-held power drills running standard chuck setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e135-degree split point reduces thrust and eliminates center-punch requirement\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web lowers cutting resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eCobalt construction with straw finish for heat resistance in ferrous and stainless applications\u003c\/li\u003e\n\u003cli\u003eStub screw machine length body provides extra rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard screw machine length replacement drill bit for use in conventional drill presses, CNC machining centers, and power drills equipped with a straight-shank chuck capable of accepting a 0.154 inch diameter tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and serviced by machinists, tool-and-die technicians, and maintenance trade professionals. Secure the straight shank firmly in the chuck before operation and confirm the drill is powered off before tool changes. Use appropriate cutting fluid when drilling stainless steel or hard alloys to manage heat buildup and extend bit life. Inspect the cutting edge and split point before each use and remove the bit from service if chipping or deformation is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 23\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.154 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Straw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSCO135\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.150 to 0.200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74130758\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51742636540210,"sku":"74130758","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2117603862f682a5872e61e0b413f032.jpg?v=1788838505","url":"https:\/\/voomisupply.com\/products\/hertel-74130758-screw-machine-drill-bit-size-23-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
